The U.S. Naval Research Laboratory (NRL) has demonstrated a laser system that can both transmit power wirelessly and defend against aerial threats, marking a significant step toward more flexible battlefield energy solutions.

The test showed that a single directed-energy platform can perform two critical military functions without requiring separate equipment. Researchers beamed power across an airfield to a remote location and then quickly switched the same system to engage a simulated drone threat.

The demonstration received support from the Office of the Under Secretary of War for Acquisition and Sustainment and the Operational Energy Capability Improvement Fund. NRL worked alongside Boeing, the Army’s DEVCOM Ground Vehicle Systems Center, and stakeholders from the Navy, Marine Corps, and Army.

The project aims to reduce dependence on fuel-based power systems while expanding the operational capabilities of deployed forces.

Power without fuel

During the demonstration, a trailer-mounted laser transmitted energy from a standard military vehicle to specialized receivers positioned at a distant site. The setup delivered power without physical cables or traditional fuel logistics.

Researchers focused on practical battlefield conditions rather than controlled laboratory environments. The team conducted testing in harsh weather, including strong winds and heavy snowfall.

According to NRL Electrical Engineer Alex Grede, the goal was to evaluate how the technology could function during real military operations. “We demonstrated that the same laser used to beam power remotely can immediately transition to counter a drone threat,” Grede said.

The ability to deliver power over distance could eventually help military units operate in remote locations with fewer fuel convoys and generators.

Built for the field

Unlike previous power-beaming demonstrations that took place under ideal conditions, the NRL team deliberately exposed the system to environmental challenges.

Researchers continued collecting data even as visibility deteriorated during severe winter weather. The results will help engineers refine the technology for future deployments. NRL Research Physicist Justin Lorentzen said realistic testing provides valuable information that laboratory experiments cannot replicate.

The team wants to understand how atmospheric interference affects performance. That data will guide future improvements and increase reliability in operational settings.

Engineers also demonstrated field maintainability during the event. The team repaired a critical component on-site and quickly returned the system to operation.

Lt. Cmdr. Brian Di Salvo, NRL Radar Division military deputy, said military systems must remain simple to operate and easy to repair. He noted that both qualities are essential for deployment in demanding environments.

Expanding military applications

The laser platform used during the test already serves the U.S. Marine Corps in directed-energy roles. Researchers integrated it with high-efficiency solar receivers and mobile vehicle power sources to create a distributed energy network.

Army requirements helped shape many aspects of the field demonstration. Officials see strong potential for expeditionary missions where reducing fuel consumption can improve both logistics and survivability.

Grede said collaboration across military branches could accelerate adoption of the technology. While NRL continues development for naval applications, the Army could become one of the first services to field the capability.

The next phase will place the system directly in front of Marines, Soldiers, and Sailors. Researchers plan to gather operational feedback and refine the technology based on how troops would use it in the field.

The effort forms part of NRL’s broader push to develop scalable directed-energy systems that strengthen battlefield resilience and extend the reach of U.S. forces.
